Introduction Polyetheretherketone (PEEK) lumbar fusion rods have been successfully used in short-segment posterior instrumentation to prevent adjacent segment degeneration. However, limited studies reported their application long-segment instrumentation. This study aimed compare the biomechanical performances of PEEK and titanium using finite element (FE) models, with expectation providing clinical guidance. Methods A FE model (A) four fixation models (BI, CI, BII, CII) L1–S1 vertebral body...

This is a broad, narrative review of the literature.In this review, we describe recent biomechanics studies on cement-augmented pedicle screws for osteoporotic spines to determine which factors influence effect cement augmentation.A search Medline was performed, combining terms "pedicle screw" and ("augmentation" OR "cement"). Articles published in past 5 years dealing with biomechanical testing were included.Several have been identified impact augmentation spines. These include type...

Abstract Purpose Both erector spinae plane block and wound infiltration are used to improve analgesia following spinal fusion surgery. Herein, we compared the analgesic effect of bilateral with in this patient population. Methods In randomized trial, 60 patients scheduled for elective open posterior lumbar interbody surgery were receive either ultrasound-guided before incision ( n = 30) or at end 30). groups received standardized general anesthesia postoperative analgesia, including...

A total of 25 consecutive patients suffering from degenerative cervical disc disease who underwent three-level anterior discectomy and fusion (ACDF) including polyetheretherketone (PEEK) cages packed with allograft were followed up for at least two years. The rate reached 72% (18/25), asymptomatic pseudarthrosis was seen in 6 but without mobility on flexion-extension radiographs, revision surgery not needed. Cage subsidence occurred one level (C67), it progressive, reoperation necessary....

Study Design. A 2-year follow-up review of 62 patients with severe rigid scoliosis (>120°). Objective. To evaluate the effectiveness and safety halo-pelvic traction (HPT) for treating Summary Background Data. Severe (>120°) is still a challenge spine surgeons. combination presurgical HPT traction, osteotomy, internal fixation could be safe effective solution these cases. Methods. We reviewed records all treated from 2013 through 2017. Radiographic measurements were performed. The...

Abstract Background Halo traction has been used as an adjunctive method in the treatment of severe spinal deformities. But there are few reports on clinical efficacy halo-pelvic (HPT) deformities complicated with respiratory dysfunction. This study was to evaluate and complications associated pre-operative HPT Methods Thirty patients dysfunction treated short-term were retrospectively reviewed. Inclusion criteria were: (1) kyphoscoliosis (coronal Cobb angle or kyphosis ≥100°) failure, (2)...
